MPROVEMENT IN TURBINE WATER-WHEEL.

Thechdula referred to in these LettarsPatent and vmaking part of thelama.

To all whom it ma/y concern.-

Be it known that I, JOHN JORDAN, of East Windsor, Berkshire county,Commonwealth of Massachusetts, have invented a new and useful ImprovedTurbine Water-Wheel; and I do hereby declare that the following is afull and clear description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

In the drawings- Figure 1 is a plan and partial sectional view of mywheel, and

Figure 2, a vertical sectional diagram, showing the interior.

In this wheel, the water is taken in from the outside circumference ofthe case K, through gateways A A A, tc., and iows out through the centreunderneath,

at B, 2.

Gates C O,f&c., are arranged in the gateways so that they may beoperated together, and simultaneously, by a peculiar mechanism, which Iwill now describe.

- Around the central shaft D, and working upon a bearing formed upon thecase at the top and around the shaft D, is placed a four-armed frame, E,with adjustable racks F F, &c., arranged so as to extend the arms G G,86o., of the frame E until the racksproper mesh in with gear-wheels H H,85e., at one side of each water-gate respectively.

These gear-wheels H H, &c.,'are placed upon the upper ends of shafts II, &c., which operate the gates themselves by means of the circular rackJ on each gate, and a pinion, K, upon each shaft I. i

When the shafts I are revolved by means of *the operation of the gear Hby the racks F, the gates O are opened simultaneously or shut, as thefour-armed frame Eis turned either way, which is accomplished by meansof the connecting-rod L attached to one of the shafts I, and extendingupward to the regulatingmechanism above.

As it is sometimes convenient to shut o the water from two or more ofthe gates, the adjustable arrangement of the racks F upon the arms ofthe frame E- allows this to be done conveniently, the shanks of thelacks F sliding in grooves, or guides formedin the arms G vof the flameE, and being set by means of bolts N N, &c.

'.lhe construction of the wheel and the alraugement of the water-guidesare as follows:

The buckets a a, Ste., are flanges set around the circumference of the-wheelame,`and inclining, from radial lines, in the direction of theflow of water.

On their inner edges, b b, &c., they increase in width from the bottomto the top, the bottom width being of about the same measurementradially as the foundation-platee at its narrowest part, d, or where thewaterguides e e, Snc., converge to the circumferential line described bythe outer edges, f, of the buckets, these guides being segments ofcircles set eccentrically to the wheel, and converging from thewater-gates toward the wheel, as -just stated. l

-Vertically the buckets a a, 85e., fill the space between the plate c atthe bottom and the top of the case O, 'i

and their outer edges are curved backward toward the `flow of water, soas to catch the full force of the stream at these points. y In theoperation of this wheel, four convergent streams, (should all the gatesbe open,) thrown to" ward the centre indirectly bymeans of thewaterguides c e,&c., and the inclination of the buckets, operate uponthe latter, each stream acting upon the buckets contained between thewater-gates and the convergent end of the guides respectively, theguides forming the outer sides of the case.

.The advantages of this construction of wheel are, that the water ismost economically used, nearly the full per cent. of power being applieddirectly against the buckets, and the latter are completely' preventedfrom being choked by ice, trash, and other foreign matter, theirinclination throwing all such toward the centre, where it is washed outby the stream.

Now, having described my invention,

What I claim as new, and desire tol secure by"Let ters Patent, is-

1. The combination of the frame E, having the adjustable racks F,with'the water-gates O, whereby the latter may be opened or closedsimultaneously, substantially as described and shown.

2. The combination of the shafts I, having gear H and pinious K, withthe circular racksJ upon the watergates @substantially as shown.

JOHN JORDAN.
